Despite the tire rating, local speed limits should be
obeyed. Use prudent driving speeds appropriate to
prevailing conditions.
Warning!
Even when permitted by law, never operate a
vehicle at speeds greater than the maximum speed
rating of the tires.
Exceeding the maximum speed for which tires are
rated can lead to sudden tire failure causing loss of
vehicle control and resulting in personal injury
and possible death.
